Question

Perform hand calculations with the use of calculators for the following problems. Do not use Excel or matlab. 1. The data for fuel efficiency of a diesel engine in a combustion test as follows: set 1 | 77.2 | 73.4 | 77.5 | 82.1 | 81.6 | 77.2 | 78.4 set 2 | 76.1 | 72.5 | 71.3 | 80.6 | 81.1 | 74.2 | 74.1 a. What is the range of the true (or population) mean of each data set for 80% confidence level? (10 pts). b. Calculate the standard normal distribution z and P(z) for data set #1. Identify any outliers data for 80% confidence level. (10 pts) c. Use Chouvenet 's criterion to identify any outliers for data set #1. (5 pts)

Step 1

Data Set 1: Mean: $\bar{x}_1 = \frac{77.2 + 73.4 + 77.5 + 82.1 + 81.6 + 77.2 + 78.4}{7} = 78.06$ Standard Deviation: $s_1 = \sqrt{\frac{(77.2-78.06)^2 + (73.4-78.06)^2 + \cdots + (78.4-78.06)^2}{7-1}} = 2.95$ Data Set 2: Mean: $\bar{x}_2 = \frac{76.1 + 72.5 + Show more…
